What is the formal charge on the hydrogen atom in hbr? use the periodic table as needed?

A covalent bond is formed between H and Br

The structure of HBr is as follows

H - Br

Formal charge for atoms are the charges for individual atoms in compounds.

Formal charge can be calculated as follows;

Formal charge of atom = number of valence electrons - (number of bonds + number of lone pair electrons)

H has 1 valence electron, 1 bond and 0 number of lone pair electrons

Formal charge of H = 1 - 1 - 0 = 0

H has 0 charge
